Mid-Miocene silicic explosive volcanism of the Tokaj Mts., eastern-central Europe: eruption chronology, geochemical fingerprints and petrogenesis
(2024)Gondwana ResearchThe Tokaj Mts. volcanism occurred in a thinning continental lithosphere regime at the final stage of the subduction process. Using high-precision zircon U-Pb dating, four major explosive eruption events were distinguished. Among them the 13.1 Ma Sátoraljaújhely and the 12.0 Ma Szerencs eruptions could have yielded large amount of volcanic material (possibly > 100 km3) and they were associated with caldera collapse as shown by the several ...Journal Article -
Exploring one giga electronvolt cosmic gamma rays with a Cherenkov plenoscope capable of recording atmospheric light fields, Part 1: Optics
(2024)Astroparticle PhysicsDetecting cosmic gamma rays at high rates is the key to time-resolve the acceleration of particles within some of the most powerful events in the universe. Time-resolving the emission of gamma rays from merging celestial bodies, apparently random bursts of gamma rays, recurring novas in binary systems, flaring jets from active galactic nuclei, clocking pulsars, and many more became a critical contribution to astronomy. For good timing on ...Journal Article -
End-to-end path planning for homogeneous temperature fields in additive manufacturing
(2024)Journal of Materials Processing TechnologyThis study explores a novel approach to path planning in deposition-based additive manufacturing, integrating the frequently overlooked process-induced temperature fields. Currently, existing approaches either ignore temperature effects entirely or only consider them in small-scale problems due to the high computational cost involved in predicting them and the combinatorial nature of path planning optimization. To address these challenges, ...Journal Article -
Hausdorff limits of submanifolds of symplectic and contact manifolds
(2024)Differential Geometry and its ApplicationsWe study sequences of immersions respecting bounds coming from Riemannian geometry and apply the ensuing results to the study of sequences of submanifolds of symplectic and contact manifolds. This allows us to study the subtle interaction between the Hausdorff metric and the Lagrangian Hofer and spectral metrics. In the process, we get proofs of metric versions of the nearby Lagrangian conjecture and of the Viterbo conjecture on the ...Journal Article -
Fabrication Procedures and Mechanical Supports of No-Insulation All-GdBCO Double Pancake Magnets in Liquid Helium
(2024)IEEE Transactions on Applied SuperconductivityThe no-insulation (NI) high-temperature superconductor (HTS) winding technique enables the fabrication of highly compact magnets with self-quench protection. NI pancake coils are implemented to develop a 28-T HTS magnet for the operation of a 792-GHz gyrotron, which is a microwave source for dynamic nuclear polarization nuclear magnetic resonance. To this end, three NI all-GdBCO double pancake (DP) magnets were fabricated using different ...Journal Article -
Influence of seed mass and shape on light plasticity of germination of alpine plants on the Tibetan Plateau: The role of photoblastic taxa, dispersal ability, and life history
(2024)Global Ecology and ConservationResponses of post-disposal germination to light play a crucial role in shaping germination niches and determining the success of seedling establishment, ultimately impacting species distribution and community composition. Seed traits are pivotal factors that influence species' germination, dispersal, and life history strategies. However, it remains unclear whether the relationship between seed traits and the light plasticity of germination ...Journal Article -
Magnetic signatures of lunar impact craters
(2024)IcarusThe Moon almost certainly had an internally generated magnetic field in its past, but the duration of the dynamo, its temporal stability, and the surface field intensity are poorly known. Impact cratering events heat portions of the crust above the Curie temperature, allowing the ambient magnetic field strength to be recorded as the crater cools. We systematically analyzed the magnetic signatures of lunar impact craters with diameters ...Journal Article -
More realistic planetesimal masses alter Kuiper belt formation models and add stochasticity
(2024)IcarusMuch of the modern Kuiper belt is thought to be the result of Neptune's migration through a primordial belt of planetesimals, possibly interrupted by an instability amongst the giant planets. While most prior work has employed massless test particles to study this Kuiper belt formation process, we perform simulations here that include the gravitational effects of the primordial planetesimal belt consisting of ∼105 massive bodies. In our ...Journal Article -
Trust at Risk: The Effect of Proximity to Cyberattacks
(2024)Journal of Global Security StudiesProximity is a core feature of theories of political violence, with the effects of attacks rippling outward so that geographically proximate individuals experience more severe effects than those more distant. However, this model of proximity and exposure is unlikely to recur for cyberattacks. The incorporeality of cyber incidents and the absence of a physical epicenter constrain the mechanism coupling physical distance with harm. To ...Journal Article -
Demonstration of a successful soft chemical stimulation in a geothermal sandstone reservoir in Mezőberény (Hungary)
(2024)GeothermicsGeothermal energy projects often lack sufficient permeability for a sustainable operation. If natural permeability is low, it can be enhanced by stimulation treatments. These can be of thermal, hydraulic or chemical nature. The challenge is to stimulate the reservoir successfully and at the same time to do it in an environmentally safe way. This is called soft stimulation and was extensively tested in the context of the EU-Horizon2020 ...Journal Article
